1. Disable functions as shown. Refer to Section 4.4,
System Setpoints
, for procedures.
2. Confirm settings to be tested. Only the winding being tested should be enabled; the others should
be disabled.
3. Connect current inputs in Configuration C1 as designated previously. See Section 6.4,
Input
Configurations
, for configurations.
4.
Select W1 in Winding Config Setpoint.
NOTE
: Special Attention must be paid as to which winding is being tested and which windings are dis-
abled.
5. Refer to Appendix D. Calculate test times for levels represented on the graphs.
It is suggested that 4 or 5 test levels be chosen.
6.
Time Test
: With output contacts connected to the timer, apply currents used in calculations from
step 4 and start timing. The operating time will be (
D
) cycles within
3 cycles or 3% of calculated
time. Repeat this step for each test level chosen. The tested points verify the operation of this
function.
7.
Observe selected winding target LED for pickup.
